holder isp'reierably made of plastic ma terial, and is light, easy to manipulate and operate, and ease-me in securely clamping the blade and in facilitating its release after the reviving operation shall have been completed.

In the accompanying drawing:

Figs. 1 and 2 are views in perspective; Fig;

showing the device closed and in the act of clamping a blade, and Fig. 2 is an open position preparatory to placing or removing a blade therefrom; g

Fig. 3 is an enlarged plan view with a portion broken away; and

, Fig. 4 is a longitudinalsection.

The numeral I represents the main portion of the holder, one end of which serves as a handle 2, and the opposite end as a support for locking lever 3.

A clamping bar 4 is connected to ,the main portion I by a hinge 5. .The razor blade 6 is seated on the main portion of the holder and the rounded teats I are placed in the usual openings 8 in the common and accepted form of safety razor of the Gillette type. The'clamping bar 4 is provided with recesses 9 to receive the ends of the teats when the clamping bar is in its closed position to hold and clamp the razor blade accurately as shown in Fig. 4. In order to apply the required clamping pressure throughout the length of the blade, means is provided for forcing the clamping bar firmly against the blade; and in my present form of construction as a simple means for doing this the looking lever 3 is pivoted at I 0 to a link I I, which in turn is pivoted at I2 to one end of the main portion I of the holder. The locking lever 3 is provided with a I3 which bears upon'; the outer end of the clamping bar 4 with increasing pressure as is swung into locking position, which pres's'ure reaches its maximum when the stop; or formed on the lowerside of the locking ieverieach'es the e inping bar as shown inFigA.

2 and 3. Then the clamping bar is swung from the position shown in Fig. 2 to the clamping position indicated in Fig. 4, andpressure is applied by swinging the link inwardly into the aligned recesses I5 and I6 whereupon the locking lever;

3 is swung over to the position shown in Figs. 1 and 4. The cam I3 exerts the required pressure on the outer end of the clamping bar 4 to effect a secure lock, and to apply the required pressure to insure holding the blade firmly and evenly between the parts I and 4.

To remove the blade, the locking lever and link I I are swungout to the position shown in Fig. 2, and the clamping bar 4 is raised and the blade may then be removed. In this way, a simple and easily operated holder is provided for clamping a blade preparatory to treatment by the use purpose, namely to hold a razor blade firmly and in proper position so that the operator may accomplish the desired results with the greatest case and safety and with the least possible danger of cutting himself during the operation.

I claim: 7

1. A safety razor blade holder including four main parts, namely a main portion, a clamping bar hinged approximately at the center thereof, and between which two parts a safety razor blade is adapted to be held, one of said parts having teats adapted to enter holes in the safety razor 7 blade, and the other part recessed to receive said blade, a link pivotally connected with one memher, and adapted to be swung into said recesses teats, a link pivotally connected with one'of said-- parts, and a locking lever pivoted to the link and having a cam eccentric with thepivot in position to bear with increasing pressure upon theother main part as the lever is swung in one directiom' 7 whereby to draw the said parts toward each other and to apply a substantially, uniform pressure 7 throughout the length of the blade held between the main portion and the clamping bar.

2. A safety razor blade holder including a main portion, a clamping bar hinged thereto between which .two parts a razor blade is adapted to be placed and clamped-corresponding ends of the mainportion and the hinged clamping bar pro- ,vided with recesses which-are adapted to be in alignment when in the position'of clamping a blade, alink pivotally connected with one membe"r, and adapted to be swung into said recesses where it is housed- Within'the recesses and supported onits sides, a locking lever pivoted to v v the link and provided with a cam which engages and exerts inward pressure upon the main portion and the clamping bar and substantially a uniform pressure upon the razor blade tween said parts, 7

3. A safety razor blade holder including a main portion, a clamping bar hinged thereto-between which two parts a razor bladeisadapted to be placed and clamped, corresponding ends of the held bevmain portion and the hinged clamping bar provided with recesses which are adapted to'be in alignment when in the position of clamping a where it is housed within the recesses and supported on its sides, a locking lever pivoted to the link and provided with a cam which engages and exerts inward pressure upon the main portion and the clamping bar and substantially a uniform pressure upon the razor blade held between said parts,- the locking lever having a stop thereon to limit its inward movement and to hold the free end of the locking lever a limited distance from the clamping lever.

4. A safety razor blade-holder including two mainparts, namely a main portion which includes a handle at one end and a fiat gripping surface atthe other end against which a safety blade is adapted to rest in contact throughout the entire transverse area of the gripping surface, and a clamping bar hinged to the main portion at a point between the handle and the flat'grip ping surface, the inner surface of which clamping bar is fiat and adapted to contact the razor blade throughout the Width of the clamping bar, whereby the razor blade is uniformly held throughoutthe entire width of the inner surface of the two members, the outer ends of the main portion and the clamping bar in substantial alignment and having aligned embracing slots or notches, and a compound fastening device which comprises a link pivoted to one mem-
